Description
Technical field
The present invention relates to a kind of method and apparatus that is used for the stranded individuality in location under emergency, relate in particular to the method and apparatus of under emergency, locating stranded individuality in the building.
Background technology
At great majority in emergency circumstances, for example when breaking out of fire or earthquake, it is very important finding timely and accurately and locating stranded individuality, because only in this way just might take effective rescue action in the very first time, thereby saves more life.So positioning system is for building; Particularly high-rise building, particularly important, because the intensive and complex structure of personnel often in the high-rise building; In case the for example emergency of fire takes place; People might be trapped in each place in the building, if there be not the auxiliary of positioning system this moment, the rescue personnel will be difficult in time know that which room or corner also have life entity to exist.
Generally speaking, the positioning system that is used for emergency condition need meet installs convenient, accurate positioning, requirement such as with low cost.Though proposed multiple positioning system in the prior art, these positioning systems still can not satisfy above-mentioned these requirements.
For example, existing GPS (GPS) is a kind of satellite-based navigational system, and is widely used in the outdoor motion object in tracking/location at present.But indoor, even gps signal also can be because of the inefficacy that takes place significantly to decay that stops of wall etc., thereby gps system is not suitable for indoor application.In addition, use GPS to need each individuality all to carry a gps receiver, this point is also unrealistic for the big public place of flow of personnel (for example, shopping center etc.), and gps receiver also is easy to lose.
Another kind of existing positioning system is called " Active Badge System (active tag positioning system) "; It requires each individuality to carry a signal generator; Be used for periodically sending unique IR/RF signal, the Surveillance center that is used to locate is collected also and then sent to this unique IR/RF signal by the receiver that is installed in known location.Similar with GPS, the inconvenience of this system is to require each individuality to carry a midget plant equally, and in case of emergency, this midget plant is easy to lose, thereby misleads the rescue personnel.
In addition, another kind of positioning system commonly used is to use the radar installations or the video camera that are installed in the building directly the body configuration to discern.This system possibly be more suitable in the public arena, but also has defective.Such as, this system needs processor at a high speed and support equipment could accomplish the complex calculation of human body identification usually, thereby system cost is considerable.And complicated algorithm also need consume suitable electric weight with device at a high speed, generally is difficult to use powered battery.Thus, when the distribution system fault, this type positioning system also can be paralysed thereupon.In addition, under the situation of for example fire and emergency escape, the interference of flame, smog and numerous and diverse background all can reduce the recognition performance of radar installations or video camera, particularly the speed and the accuracy of identification.
Therefore, existing positioning system can't reach the requirement of in case of emergency assisting the rescue personnel effectively to carry out rescue work.

To understand in order technical characterictic of the present invention, purpose and effect being had more clearly, to contrast description of drawings embodiment of the present invention at present.
Below will be that example is described device and the system that is used in case of emergency locating stranded individuality according to of the present invention with the scene that building catch fire.But, it should be appreciated by those skilled in the art that locating device and system that the present invention proposes are not limited to the building application, can also be applied in some outdoor occasion.
Fig. 1 shows the exemplary scenario that building catch fire.In Fig. 1, suppose that building 100 comprise 3 floors, each floor comprises 3 rooms.As shown in Figure 1, traditional fire alarm system has been installed in building 100.This fire alarm system comprises the detector 110 (for example smoke detector) that is arranged in each room; And be connected to a Surveillance center 130 of these detectors 110 through being distributed in signal transmission network 120 in the building, wherein each detector 110 has the location tags of its installation site of expression.In case certain detector 110 detects the smog or the condition of a fire, condition of a fire spot is just located according to the result of detection and this position of detector label that send from this detector immediately by Surveillance center 130.In example shown in Figure 1, Surveillance center 130 can orient at the 1-3 layer all has the condition of a fire to take place.But Surveillance center has no way of being informed in the 1st layer the 1-1 room in building as shown in Figure 1 and the 2nd layer 2-3 room also has two personnel A and B to be trapped within doors respectively.
In scene shown in Figure 1, be disposed on the detector 110 according to the positioning equipment 200 of the embodiment of the invention.In Fig. 1, for simplicity, two positioning equipments 200 only are shown, but in fact on each detector 110, a positioning equipment 200 can be installed.Perhaps, according to actual conditions, a plurality of positioning equipments 200 also can be installed and be connected on the same detector 110.Each positioning equipment 200 can equally store a label (ID) relevant with its installation site in advance as detector 110.For example, this ID can be floor number, room number, location number or the like.For another example, this ID also can only be the sequence number of this equipment, and this ID is associated in its installation site at the Surveillance center place.
Fig. 2 shows the concrete structure of positioning equipment 200 among Fig. 1.As shown in Figure 2, according to one embodiment of the invention, positioning equipment 200 can comprise sound receiver 210, treating apparatus 220 and dispensing device 230.In example shown in Figure 1, positioning equipment 200 and the shared same distribution system of fire alarm system, and dispensing device 230 is via the existing transmission network 120 transmission signals of this fire alarm system.
Fig. 3 schematically shows the operational flowchart according to the positioning equipment 200 of the embodiment of the invention.To combine Fig. 2 and Fig. 3 to describe operating process in detail below according to positioning equipment of the present invention.
As shown in Figure 3, positioning equipment 200 starts its receiving trap 210 of back will continue reception/collected sound signal, and convert voice signal into electric signal (step S310).Preferably, for fear of collecting a large amount of unnecessary acoustic informations, positioning equipment 200 can only just start after emergency condition takes place by (fire alarm for example occurring), and the present invention is not limited thereto certainly.When the condition of a fire appears in the building, be confined in the building if any individuality, this stranded individuality tends to send an SOS through variety of way.For example; As shown in Figure 1; Stranded individual A may cry out lustily for help, and for example calls out " help ", " SOS " etc., and stranded individual B maybe be because of various reasons sends the emergency sound of the repeatability of "------" through knocking (for example knock wall, desk or clap the hands etc.).At this moment, the receiving trap 210 that is positioned near the positioning equipment the stranded individuality can capture this emergency sound.Here, alternatively, receiving trap can also comprise an A/D converter, and being used for the speech simulation conversion of signals that collects is digital signal, handles so that treating apparatus 220 carries out the identification of numeric field.But, as it will be appreciated by those skilled in the art that, the present invention is limited to this, and the signal analysis of analog domain can be used to carry out identifying operation equally.
The voice signal that receiving trap 210 is received further is sent to analyzes and discerns (step S320) in the treating apparatus 220.As stated; The distress signal that stranded individuality sends (for example has uniqueness usually; It possibly be repeated signal (------) or have fixed mode signal (like " SOS " signal)), thereby through this distress signal being carried out suitable analysis or handling and can it differentiated from the mixed and disorderly ground unrest that is caused by the condition of a fire.To the distress signal of different mode, treating apparatus 320 can adopt different algorithms to analyze and discern.
Be example at first below, describe the identifying of treating apparatus 220 in conjunction with Fig. 4 with the series of periodic distress signal of for example "------".As shown in Figure 4, at first, treating apparatus 220 is monitored the input signal that receives from receiving trap 210 always, and whether amplitude or the energy of promptly monitoring this signal have exceeded a predetermined threshold value (step S410).If exceed threshold value, then show and find a possible distress signal, for example find first " " signal S1.In step S420, treating apparatus 220 continues to search whether have a follow-up possible distress signal.For example; Treating apparatus 220 can compare the energy of next possible distress signal and the signal energy of S1; Perhaps can calculate this two related coefficient, whether the two is the signal (as shown in Figure 6) of repetition thereby determine this, and the present invention also is not limited to this two kinds of methods certainly.After finding the possible distress signal of a series of repetitions, in step S430, the distress signal whether definite a series of possible distress signal that is found is behaved and sent.For example, in this example, if in this series of signals the interval time between each signal within rational range of tolerable variance, then confirm as and identified the distress signal that produces by indicator of trapped personnel, promptly found indicator of trapped personnel (step S440).
Recognition methods shown in Figure 4 only is exemplary.In according to other embodiments of the invention, above-mentioned recognition methods can also be replaced by Spectral Analysis Method or related operation method etc.In another embodiment, distress signal also possibly be to have fixed mode signal, " help " sound of for example being called out out by stranded individual B.For this fixed mode distress signal, treating apparatus can be stored some predefined known emergency sound templates in advance.After receiving the possible distress signal that exceeds threshold value, can determine whether it is the distress signal that indicator of trapped personnel is sent through the similarity between this possible distress signal and the predefine template relatively.The two also can be used in combination repeatability pattern and fixed mode.
In addition, preferably, for fear of wrong report, treating apparatus 220 can also filter the voice signal that receives, to get rid of the voice signal that non-human produces.For example, sound such as music, quarter-bell have periodically equally, but its cycle is accurate and can reach the hundreds of Cycle Length of second, and this is that the mankind can't produce.To this situation, the filtrator filtering cycle capable of using accurately and the signal of excessive cycle.In addition, the sound that sends because of the fracture of building structure torsional deformation or metal tube when fire takes place, also possibly occur, the change of frequency of these sound has accurate acceleration or the retarded velocity that the mankind can't produce usually, thereby filtrator capable of using is with its filtering.Can be applicable to filter method of the present invention and be not limited to this, those skilled in the art can also use any other suitable filtering method according to the actual requirements.
In case in the step S320 of Fig. 3, identified indicator of trapped personnel, then this recognition result together be sent to a Surveillance center (step S330) via the transmission network 120 of fire alarm system with the ID relevant with device location by dispensing device 230.Preferably, dispensing device 230 can be used to identify a sign whether finding indicator of trapped personnel with and the ID relevant with the position send to Surveillance center so that the flow of minimized.Alternatively, with recognition result, dispensing device 230 can also send to the parameter of a series of distress signals that identified Surveillance center, for example voice signal frequency, cycle, signal amplitude etc.Perhaps, can also the fragment of the distress signal that is identified be sent to Surveillance center, so that Surveillance center examines and confirms.For those wrong reports or relate to the fragment of sound of privacy, Surveillance center can remove after affirmation voluntarily.
At last, Surveillance center goes out the position of indicator of trapped personnel according to the data locking that receives from positioning equipment, and guides the rescue personnel to search and rescue to the indicated position of this ID relevant with the position in view of the above.Preferably, Surveillance center can also be according to carrying out more accurate localization from the data (like recognition result or voice signal) of adjacent several positioning equipments.For example, if 2 positioning equipment A in adjacent 4 positioning equipments and B all identify the distress signal that indicator of trapped personnel is sent, then Surveillance center confirms to have the stranded and position of personnel near positioning equipment A and B one side.This point can improve the bearing accuracy to indicator of trapped personnel effectively.。
